To provide a driver alert system capable of improving the safety. A bicycle includes a first transmission circuit transmitting a first ultrasonic wave, a first receiving circuit receiving a second ultrasonic wave, an arithmetic circuit detecting the presence or absence of an object from the second ultrasonic wave, and a second transmission circuit transmitting a third ultrasonic wave. A driver wears a second housing including a second receiving circuit receiving the third ultrasonic wave. The arithmetic circuit includes a first selection circuit selecting a potential based on the second ultrasonic wave at a different timing, a plurality of signal retention circuits retaining a potential based on the second ultrasonic wave, a second selection circuit selecting any one of the plurality of signal retention circuits, and a signal processing circuit to which a signal selected in and output from the second selection circuit is input. The second selection circuit selects the plurality of signal retention circuits at different timings to generate a signal obtained by delaying the second ultrasonic wave. The third ultrasonic wave generated on the basis of the signal is transmitted to the second housing.

A straddle type vehicle includes a front cover configured to cover a front part of the vehicle, and a detecting unit for detecting a situation in front of the vehicle. The detecting unit is arranged behind a central portion of the front cover in a vehicle width direction. A gap is formed between the detecting unit and the front cover in a vehicle longitudinal direction and a viscoelastic member is installed in the gap.

The disclosed method may include configuring one or more brakes based on a braking-related attribute expected at a geographic location being traversed by a personal mobility vehicle. By configuring the application of brakes of a personal mobility vehicle based on terrain, environmental conditions, and other geographic features, the system may reduce the risk of the vehicle skidding or tipping due to over-braking. In some embodiments, a rider may use a single brake lever to indicate a desire to brake and the system may make determinations about how to apply a combination of mechanical and electrical brakes to front and back wheels based at least in part on the location of the personal mobility vehicle. By configuring brake engagement based on a combination of controls and map data, the system may improve user experience and user safety, especially for inexperienced riders.

A straddle type vehicle includes a front detection unit configured to detect an object in front of a self-vehicle, a first determination unit configured to determine whether there is an avoidance space for avoiding contact with the object by turning in a case where there is a possibility of contact of the self-vehicle with the object, and a notification unit configured to give notification of information regarding the avoidance space in a case where the first determination unit determines that there is the avoidance space. The notification unit gives notification of information, as the information regarding the avoidance space, indicating that it is possible to avoid contact with the object by turning in a travel lane in which the self-vehicle is traveling.
